Why is Telnet Blocked?

Postby Cinema on Fri Apr 13, 2012 11:28 am

Anyone know why the uni blocks telnet connections? And is there a way around it?

What do you even need telnet for? It is obsolete & insecure, anything that requires that sort of interaction should be using SSH instead. Incidentally, SSH is also blocked.

Actually, SSH would work just fine too, but it might pose a problem for certain clients.

The purpose would be for MUDing. I can already do so at campus through a Flash client (so essentially through a proxy), but the Flash client is lacking in features. It is practically like MUDing on a telnet client! Haha!

Anyway, I'll add another discovery: it is an eduroam thing, because I'm currently in Ireland on eduroam and noticed it is blocked here too.

Probably for security, as you say, but why SSH as well then? I bet this is annoying for the Computer Science students.

The Computer Science subnet has none of the restrictions that halls/eduroam do, so any CS students living in halls can just route all of their traffic via a machine in CS.

Students used to be able to request SSH access to one of the University's 'main Unix servers' if they had a legitimate reason. I'm not sure whether they still take such requests or whether they would consider MUDing to be a legitimate reason, but there would be no harm in trying.
